By default, this extension prevents buttons from displaying in the message pane (including the compact header extension buttons). To restore them to the main toolbar, use the Customize menu option. The options extension lets you restore them to the message pane if you prefer (Tools > Add-ons > Extensions > Classic TB2 Options).

For Windows users, the Titlebar Tabs Cleaner extension is recommended to restore the classic titlebar appearance.

Known issues:

The tab close button is still missing for Unix/Linux users. Fix coming soon!

Some Windows 7 users have a missing titlebar.

In Unix/Linux the dropdown menu arrow is doubled, the right menu arrow is missing, and some text colors are not optimal.

The options dialog currently has English, French, and German translations (Italian coming soon). If you can help with other languages, please send an email.

Thanks for all of the bug reports! They are a big help in fixing issues with screens I don't use very often.
